To all whom t may concern:

Be it known that I, CHARLEs E. TAYLOR, a citizen of the United States,and residing at Methuen, cgunty of Essex, and State of Massachusetts,have invented an Improvement in Filling-Detectors for Looms, of whichthe following description, in connection with the accompanying drawings,is a specification, like characters on the draw-v loom, and upon theoccurrence of substantial exhaustion of the filling in the shuttle,setting into operation mechanism for effecting replenishment of thefilling supply. In some types, the detecting means has consisted of twomembers, one an impinging member to contact with means, such as thevfilling in the shuttle, and the other a penetrating member to sink intothe filling'on each detecting beat-up movement of the lay, and upon theoccurrence of substantial exhaustion of filling, these members have co-`operated to initiate filling replenishment.

Mechanism of this type is shown and described in the patent to C. F.Roper, No. 821,123., .dated May 22, 1906, which has in a large measureworked satisfactorily.

In detector mechanisms comprising a'n impin-ging member and apenetrating member,' it is desirable that there should be capacity forrelative adjustment of the two members toward and from the lay in orderto determine the most advantageous degree of penetration of thepenetrating member with respect to the particular yarn or filling on thebobbin or carrier in the shuttle, and this has been suggested in thepatent mentioned. lVhere the impinging member extends for some distancelongitudinally of the bobbin axis and consequently impinges upon thefilling at different points longitudinally `of the'. lling mass, it is'desirable that the impinging and penetrating members be not onlyrelatively adjustable in a direction toward and from the lay to regulatethe degree of penetration of the penetrating member, but that thc'impinging member be adjustable in a direction angularly to the bobbinaxis or with relation to the penetrating member in order that asubstantially flush bearing be secured between the filling mass and thefull length of the impinging member.

An important feature of the present invention, therefore, consists inproviding a filling detector of the impinging and penetrating type, withmeans for relatively adj usting the two members angularly .and bodilytoward and from the lay. Where such angular adjustment is made by theimpinging member, it is liable to disturb the relation of the twomembers which determines the degree of penetrability of the penetratingmember, and the present invention, therefore, further provides that theim# pinging member be adjustable both angularly and rectilinearly withrespect to the penetrating member.

As well understood by those familiar with 1 those devices, the detectingaction and initiation of filling replenishment must be efectedin a very`small fraction of time during the detecting beat of the lay;therefore,sim plicity of construction and operation conduce to a moreaccurate accomplishment of the desired end.

Another important feature of the invention, therefore, consists inoperatively positioning the means for .initiating replenishment .bysimple and positive means, which, in the embodiment of the inventionhere illustrated, comprises a rocker which may be turned upon its axisthrough a small arc when the penetrating member strikes the more dense"substance of the filling carrier or bobbin.

Otherv features of theinvention will be hereinafter described inconnection with the illustrated embodiment of the invention, and thendefinitely set forth in the claims.

In the drawings Figure l is a plan view of the filling detector, showingthe action of the impinging and penetrating members when aworking'supplyof lilling is-present in the shuttle;'Fig. 2 is a section on the line2-2, Fig. 1; Fig. 3 is a plan view similar to that of Fig. 1, showingthe position of parts on the beat-up movement when the filling issubstantially exhausted; and Fig. 4 is a section on the lined-Jl, Fig.3.

The detecting mechanism of the present invention-is adapted forapplication to a s0- called filling replenishing or automatic loom,wherein upon substantial exhaustion of the filling in the shuttle, meansare set in operative condition to eiect replenishment of the filling.The replenishing mechanism and its general characteristics andoperations, as well as the parts for initiating its operation, under thecommand of the detecting mechanism, are Well understood by those skilledin the art, and detailed explanation thereof 1s unnecessary.

The shuttle S is provided with an opening 2 in its side wall, and theshuttle-box A has its front wall 3 provided with an opening 4, the saidopenings in the' wall of the shuttle and shuttle-box being adapted toregister when the shuttle is properly positioned in said box for theaction of the detector mechanism. These features also are common andwell understood.

The illing detector comprisesa stand 5 which may be properly secured toa suitable portion of the loom frame in which the deteptor is to be usedby the means such asfthe screws 6, and is provided with bearing portions7 and 8 in which .is mounted the eeler carrier 9 and itsforwardly-projecting stem 10, said stem being under the control of asuitable spring 11 normally tending to orce fthe feeler carrierrearwardly or toward the lay. In the present instance of the inventionthe feeler is, shown as a slide and the spring 11 surrounds the stem 10and at one vend is seated against the bearing 7 and at the otherendagainst an enlarged portion of the feeler slide, substantially asusual in this such impinging member class of devices, and as clearlyindicated in Figs. 1 and 2.

The term feeler slide is herein employed in its broad sense as a partfor carrying the ,feeler members and movable toward and from the frontof the loom.

The feeler slide 9 has at its rear portion, an impinging member 12,which, when the shuttle is in the box at the detecting side ot the loom,is adapted to enter and contact with the filling or filling carrier inthe shuttle. The impinging member 12 is adjustably mounted to the headportion 13 of the feeler slide 9, both for angular and rectilinearmovement with respect to the slide. In the present form of theinvention, this adjustment is secured by means of a screw 14 whichpasses through an elongated opening 15 in the impin'ging member 12,whereby may be adjusted bodily or rectilinearly with respect to thefeeler slide head 13. The eeler. slide head 13 is preferably providedwith a seat to receive the impinging member 12, there beinging member tobe angularly adjusted in order to bring its impinging edge 17 into ingmemes proper relation with the axis of the bobbin' or the filling masswound thereon. l

Extending through the head 13 of the feeler slide, is the penetratingmember 18, the penetrating end portion of which also extends through asuitable opening at one end portion of the impinging member,substantially as indicated at 19, Fig. 1. In order that the penetratingmember may be limited in its movement relative to the impinging memberor the head 13, a pin 20 passes through the head 13 and an elongatedslot in the penetrating member,y substantially as indicated in Fig. 3.

From the construction thus far described, it will be apparent that theimpinging member 12 may be adjusted rectilinearly with respect to thefeeler carrier or vslide to relatively position the impinging edgeportion 17/ of the impinging member and the penetrating portion of thepenetrating member; and likewise the impinging member 12 may beangularly adjusted to bring its impinging edge portion 17 intosubstantial parallel relation with the axis of the bobbin or with thefilling mass wound thereon, so that such impinging member may contactwith the lling mass, substantially throughout the extent of itsimpinging edge portion.

Rising from the head 13 of the eeler slide is the' lug 21 in which ismounted the stud 22 on which the finger 23 is pivotally mounted. Thefree end portion 24 of the finger 23 is provided with a notch which isadapted at times to engage a controller 25 for initiat-v llingreplenishment when such eeler 23 is moved toward the front of the loomwhile engaged with the controller.

In order to control the operative or inoperative position of the finger23 with' re- 105 spect to the controller, the present inventioncontemplates a rocker mounted independently of the finger and normallyunder the influence of means for holding the penetrating member of thedetector in projected po- 110 sition, and operative connections areprovided between such rocker and finger 23 to control the position ofthe finger.

In the present embodiment of the invention, the rocker comprises a part26 piv- 11i otally mounted at 27 tothe eeler slide and normally underthe control of a spring 27x disposed between one end of the rocker 26and a shoulder 28 of the feeler slide. Oppositethe spring 27)c therocker 26 bears 120 upon the end 29 of the penetrat'ng member of thedetector, and normally seiLves to hold 'such penetrating member inprojected position with respect to the impinging member.

Extending upwardly from the rocker 26 at 125 the 4opposite side of itspivotal mounting 27 is a projection 30Yadapted to engage a lug 31extending downward from' the finger 23, the construction being such thatwhen the rocker 26 is in normal position, as indicated I13e rontward onthe beat-up movement of the lay, the penetrating member turns the rocker26 upon its pivotal mounting 27 and perforce, turns the finger 23 tobring its bi.- furcated end portion 24 into position to engage thecontroller 25 when the detector or feeler slide is moved toward thefront of the loom.

The nger 23 has a rearwardly extending lug portion 32 through whichextends an adjusting screw 33, the end portion of which is adapted tocontact with the top portion of the feeler head, when the bifurcated end24 of the finger 23 is'in inoperative relation with the controller 25,substantially as indicated in Fig. 2.

From the construction described, it will be apparent that the rocker 26is mounted independently 'of the finger 23, and by turning movementthereof -due to the penetrating member of the detector engaging thedense substance of the filling carrier or bobbin, such rocker is turnedupon its axis to thereby position the finger 23 operatively and initiatefilling replenishment upon the forward movement of the detector.

The construction is simple and effective, and the parts so related thatwithin a small space of time allowed for the action of the detector,upon substantial exhaustion of filling, the parts may assume the desiredrelation for initiating filling replenishment.
